While I'm usually quietly behind the scenes consulting for the next generation of aquarium LED lights, I had to share this breakthrough by Dr. Santhanam and his team that was recently published in Physical Review Letters: LEDs that actually cool their surroundings, turning heat energy into visible light energy! And just as incredibly, have an efficiency of over 200%.
Pause for a moment to let that sink in.
No heatsinks, no chillers, no heat degredation of the emitters or associated electronics, but a light source that actually cools its surroundings and emits more light energy than it consumes in electricity. Lighting's holy grail?
While the cooling effect isn't "significant", at least as of yet, the sheer fact that heat isn't produced is astonishing, not to mention usefu and incredibly efficient. Instead of energy being wasted as heat, it's converted to light, further increasing the luminous efficacy.
